CHARLES L. MGCUEN, 0F DETROIT, MICHIGAN, ASSIGNOR, BY MESNE'ASSIGNMENTS,TO THE ISKO COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

REFRIGERATING DEVICE.

Application filed November 15, 1917.

To all whom t may concer/n.'

Be it known that I, CHARLES L. MCCUEN, a citizen of the United States,and resident of Detroit, Wayne county, State of Michigan, have inventedcertain new and useful Tmprovements in Refrigerating Devices, of whichthe following is a specification.

This invention relates to refrigerating devices and particularly tosmall refri erating units specially adapted for domestic use.

One of the objects of the invention is to provide a simple andeiiicient'construction of the driving connections from the motor to thecompressor and other driven parts of the device.

Another object of the invention is to provide a novel and convenientarrangement of the various parts of a refrigerating unit to therebyfacilitate the driving connections and adjustment of the parts'.

Other objects of the invention will appear from the followingdescription taken in connection with the'drawings which form a part 0fthis specification, and in which:

Figure 1 is a plan View of a refrigerating device embodying thisinvention; and

Fig. 2 is an elevation of the device shown in Fig. 1 with part of thecondenser or radi-` ator broken away.

Referring to the drawings, 10 represents a supporting base upon whichthe var1ous parts of the refrigerating unit are mounted. A condenser orradiator 11 is arranged in an upright position at the front of the base,and at its rear a casing or shroud 12 is provided having a circularrearopening 13 in which a fan 14 is arranged. It will be u nderstood thatthe operation of the fan 14 will cause an intensiiied flow of airthrough the radiator and thereby assist greatly in convdensating therefrigerant iiowing therethrough.

At the'rear of the condenser and at one side of the base is -mounted anupright cornpressor 15 connected as by a pipe 1 6 .with the condenser.This compressor is provided with a driving pulley 17 and it is adaptedto be driven by an electric or other motor 18 also mounted on the base10 at the rear of the condenser. The motor 18 has a pulley Specificationof Letters Patent.

Serial No. 202,161.

19 in line with the pulley 17 of the. compressor and a belt 20 extendsbetween these pulleys for connecting them. The motor 18 is preferablymounted on the base so that it may be moved toward or from thecompressor to thereby adjust the tension of the belt 20. Thisconstruction includes the slots 21 in the base l() and bolts 22extending through the slots and through ears 23 in the motor casing.Thus it will be understood that the motor may be moved lengthwise of theslots 21 until the belt is suitably tightened and thebolts 22 will thensecure the motor in its adjusted position.

Mounted on the base between the motor and the compressor is a bracket 24having Patented Nov. 9, 1920. l)

a bearing 25 for a pulley 26, which pulley is arranged in line withpulleys 17 and 19 and to be driven by the belt 20 which passes over itas shown in both figuresl of the drawings. This bracket 24 mounts itspulley 26 so that the aXis thereof is in line with the laxis of thefanlt arranged in the opening 13 of the radiator shroud and the fan isdirectly connected to the pulley so that it may be driven by the latter.This provides an extremely simple and convenient means for driving thefan from the compressor driving mechanism and no additional belts orgearing are required.

It will be understood that my invention is not limited to the details ofconstruction shown, and other forms may be used without departing fromthe spirit or scope of the invention.

Having thus described my invention, what l `of a fan arranged betweenthe compressor and motor and operative with reference to the condenser,and a belt for driving the compressor and fan from the motor.

3. ln a refrigerating device, the combination with a compressor, a motorseparated therefrom, and an elongated condenser arranged alongside themotor and compressor, of a fan arranged between the compressor and motorand operated by the latter, and a 10 shroud inclosing the condenser andfan'.

In testimony whereof I ax my signature.

CHARLES L. MCCUEN.
